it's 6 a.m. here at the Miami International Airport and Permanent Construction Zone. I'd like to buy a newspaper, but I can't: The newspaper stand on my concourse isn't open yet. Must be too early for them, even though there are thousands of people here waiting for planes. Fortunately the airport p.a.-system volume is cranked way up, so while we sit, not reading newspapers, we can enjoy the sound of loud airport pseudojazz. Nothing like a wailing sax at 6 a.m., except maybe root canal.
